1. Model Code Explanation

• CACR: Classic Yaskawa Yasnac VS800 full-digital AC Servopack series for CNC feed axis application

• SR: Multi-mode drive, supports speed / torque / position control via parameter setup

• 07: Rated for 0.7kW servo motor, rated continuous output current: 7.6A

• A: Standard original main control PCB without hardware revision

• C: Only ±10VDC analog command input (speed/torque instruction), no pulse positioning input

• 1: Factory default base firmware

• E: CN2 feedback port exclusively for USAREM incremental encoder motors

• S: Basic standard hardware platform

• -Y105: Special OEM customized firmware version; core parameters locked by original equipment manufacturer, partial function & IO definition fixed per machine manufacturer’s requirement (cannot fully reset or modify all parameters like standard CACR-SR07AC1ES)

2. Electrical Specifications

• Main power supply: 3-phase AC200V~230V, tolerance: -15%~+10%, 50/60Hz

• Independent single-phase AC200V~230V for control power input

• Overload capacity: 150% rated load sustainable for 60s; 300% peak overload lasts max 3 seconds

• DC bus: DC280V~320V; P/N terminals reserved for external regenerative braking resistor connection

• Drive type: IGBT sine-wave PWM drive, dual closed-loop of current & speed control

3. Environmental & Mechanical Data

• Operating ambient temperature: 0℃ ~ +55℃; storage temperature: -20℃ ~ +70℃

• Humidity: 5%~80%RH non-condensing; protection grade IP20

• Cabinet vertical mounting; max working altitude ≤1000m above sea level

• Net weight: approx 2.0kg

4. Interface Description

• CN1: Opto-isolated digital I/O terminals, I/O logic predefined by Y105 OEM program (different from standard S-version)

• CN2: Dedicated incremental encoder connector matching USAREM servo motors only

• Built-in proprietary RS422 serial port for parameter readout and drive status monitoring
